基于 C/S与B/S混合模式的重症肌无力管理系统的设计与研制

重症肌无力临床医生在就诊过程中收集了大量的临床资料,但是面对庞大而又杂乱的临床资料,人工对其进行管理、查询、统计分析等显然不可取,费时费力且更不用说从中“挖掘”出有用的信息以辅助诊断;此外,对于病人服药情况、疗效的随访等也难于开展,更不用说在医院各科室内部、Internet上共享临床资料。基于此,本文开发了以C/S和B/S混合模式的重症肌无力信息系统,以期为临床和科研做出一定的贡献。     

不同年龄高血压大鼠血管平滑肌中ERK和MKP-1的表达

目的：研究不同年龄的自发性高血压大鼠（SHR）和Wistar Kyoto大鼠（WKY）主动脉平滑肌中丝裂原活化蛋白激酶（MAPK）及其磷酸酶（MKP-1）的表达及其与高血压的关系。 方法： 用tail-cuff测量大鼠尾动脉血压；分别用Western blotting法和RT-PCR法半定量测定血管平滑肌中磷酸化细胞外信号调节激酶（p-ERK）和MKP-1的蛋白表达以及MKP-1 mRNA的含量。 结果： （1）SHR的血压自8周龄起明显高于WKY（P<0.01），且随年龄增长而升高（P<0.05）至14周以后趋于稳定；（2）SHR主动脉平滑肌中的p-ERK表达明显高于同年龄的WKY（P<0.01），随年龄增长而递增（P<0.05），与血压呈正相关；（3）SHR主动脉平滑肌中MKP-1蛋白明显高于同龄WKY，而mRNA的表达在5周龄时明显高于WKY，之后均随年龄的增长而递减（P<0.05），与血压和ERK呈负相关，而WKY下降不明显。 结论： MKP-1在高血压的发生和发展过程中起重要作用，其表达逐渐下降可能是导致ERK激活增加，从而导致血管平滑肌细胞增殖、血压升高的重要原因。

Epstein-Barr virus-associated smooth muscle tumor in patients with acquired immunodeficiency syndrome.

Epstein-Barr virus (EBV)-associated smooth muscle tumor (SMT) is a recognized but uncommon disease that is found to occur in patients with immunocompromised conditions such as acquired immunodeficiency syndrome (AIDS). These tumors may be multifocal and located at unusual sites, such as the brain and liver. This report describes the case of 2 AIDS patients with EBV-associated SMT and highlights the features and outcome of this rare but potentially important tumor in human immunodeficiency virus management.     

A randomized study comparing the use of sublingual to vaginal misoprostol for pre-operative cervical priming prior to surgical termination of pregnancy in the first trimester

BACKGROUND: Misoprostol is an effective agent for pre-operative cervical priming before surgical termination of pregnancy in the first trimester. Previous studies have shown that both oral and vaginal routes are equally effective for such a purpose. This study aimed to compare a new route of sublingual administration to the vaginal route of administration for pre-operative cervical priming in first trimester surgical abortion. METHODS: Eighty women with gestational age <12 weeks were randomized by a computer-generated model to receive 400 micro g of misoprostol either sublingually or vaginally 3 h prior to vacuum aspiration. The primary outcome measure was the degree of cervical dilatation, and secondary outcomes included the force required to dilate the cervix from 3 to 8 mm, intra-operative blood loss and incidence of pre-operative side-effects. RESULTS: There was no significant difference in the baseline cervical dilatation (sublingual: 7.6 +/- 1.3 mm; vaginal: 7.7 +/- 0.73 mm), cumulative force required to dilate the cervix from 3 to 8 mm (sublingual: 9.0 +/- 9.8 N; vaginal: 6.6 +/- 5.4 N) and total blood loss (sublingual: 52.1 +/- 20.2 ml; vaginal: 48.3 +/- 12.3 ml). Pre-operative side-effects were also similar. CONCLUSIONS: Both sublingual and vaginal misoprostol are effective in cervical priming before surgical termination of pregnancy in the first trimester. Sublingual misoprostol has the advantage of being more convenient to administer and may be more suitable for day surgery.     

Expression of a G-protein {beta} subunit-related gene during lymphocyte activation

Using a subtractlve strategy, we have cloned an activation-relatedgene from a human B cell cDNA library. Sequence analysis revealedthat this gene was identical to H12.3, a gene belonging to anexpanding family of guanlne nucleotlde-blndlng protein ßsubunlts. The expression of H12.3 was induclble in the latephase of mltogen-stlmulated T and B cells. In T cells, IL-2and IL-4 by themselves had no direct effect on the expressionof H12.3, but they could augment the level of steady-state H12.3mRNA stimulated by phytohemagglutlnln. On the other hand, IFN-and IL-6 had no obvious effect on the expression in B cellswith or without Staphytococcus aureus Cowan l-stlmulatlon. CyclosporinA, a strong immunosuppressant, Inhibited the mltogen-stlmulatedexpression of H12.3, but rapamycin, another such agent, didnot. In synchronized Jurkat cells, the expression of H12.3 hadno cell cycle-dependent decrease in S and G₂/M phase, whilecyclin E, which controls the progression of the cell cycle unlate G₁ phase, did show a periodic expression pattern. The resultssuggest that H12.3 might be involved in regulation of lymphocyteactivation.     

Genetic alterations in primary and secondary hyperparathyroidism

Hyperparathyroidism refers to a term representing a wide spectrum of parathyroid disorders that are characterized by the increased production of parathyroid hormone. Hyperparathyroidism was once thought to be tare but is now more commonly recognized, aifecting 1 in 500 women over 40 years of age. Yet the interpretation of parathyroid pathology is still controversial and confusing. Over the past 10 years, genetic changes ( ret and menin genes) involved in the pathogenesis of MEN 2 and MEN 1 have been discovered in succession. Different mutations of the calcium-sensing receptor gene have been identified in neonatal severe hyperparathyroidism and familial hypocalciuric hypercal-cemia, respectively. The HRPT 2 gene responsible for the development of heredltaty hyperparathyroidism and jaw tumors has been localized on the 1q21–31 locus. Several genetic alterations have also been characterized in primary and secondary hyperparathyroidism. Different genetic alterations appear to involve the development of different types of hyperparathyroidism. These novel advances give us new insights into the pathogenesis of hyperparathyroidism and allow better differentiation between the different types of parathyroid disorders.

大鼠催乳素瘤形成过程中催乳素基因的表达

给ＳＤ大鼠皮下埋植内含１７β－雌二醇硅橡胶管３０、６０、１２０天后，发现大鼠垂体重量随给药时间延长呈持续性增加；用放射免疫法测定血浆催乳素含量，亦依次明显升高；用Ｎｏｒｔｈｅｒｎ印迹杂交方法检测垂体细胞中ＰＲＬ基因，发现ＰＲＬ ｍＲＮＡ含量也依次显著增加，但其增加却远低于血浆ＰＲＬ含量的增加，提示β－雌二醇除了促进ＰＲＬ基因的转录外，还可能增加ＰＲＬ ｍＲＮＡ的翻译效率。
